Physicists have teleported quantum information from one ensemble of atoms to another 150 metres away, a demonstration that paves the way towards quantum routers and a quantum Internet. One of the enabling technologies behind a quantum internet will be quantum routers capable of transmitting quantum information from one location to another without destroying it.
That’s no easy task. Quantum bits or qubits are famously fragile—a single measurement destroys them. So it’s not all obvious how macroscopic objects such as routers in a fibre optics network can handle qubits without demolishing them.
It relies on the strange phenomenon of entanglement in which two quantum objects share the same existence. That link ensures that no matter how far apart they are, a measurement on one particle instantly influences the other.It is this ‘influence’ that allows physicists to transmit quantum information from one point in space to another without it passing through the space in between.
There are many videos available online on youtube. This is one which I liked the most.
